Delete a user / Disable a user

Currently you are unable to delete any user from the timeION. It's done on purpose, to keep reports data integrity.
You are only able to disable a user. 

Go to SETTINGS->Team and then use "Disable" action, which is presented as an eye icon.
Disabling a user will remove it from all the views of the app, but it will remain in the database, so you could enable a user again if you change your mind.
